METHOD OF FORMING GARMENT-STAYS.

Specification of Letters Patent.

Patented Mar. 20, 1917.

Application filed September 13, 1915. Serial No. 50,333.

To all whom it may concern:

Be it known that I, CHARLES R. NELSON, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in the Methods of Forming Garment-Stays, of which the following is a specification.

This invention relates to the method of forming garment stays and the like and consists in certain improvements therein as will be hereinafter fully described and pointed out in the claims.

The object of the invention is to simplify the production of such stays and to improve the quality thereof. In carrying out the process, the following mechanism may be used:

Figure 1 shows a plan view of a machine for this purpose. 1

F ig. 2 a central section of a portion of the machine on the line 22 in Fig. 1.

1 marks the frame of the machine, 2 the die bed and 3 the dies. These dies have the openings 4 and 5 in which operate the punches 6 and 7. The punches are carried by a chuck or head 3. The head is guided by the pins 9 which enter the perforations 10 in the die block 2. The punch is operated from any well-known reciprocating mechanism by means of a plunger 11. The punches are set so as to slot a metal strip as 13 alternately from opposite edges, the resulting fabric being shown at 13.

The strip is fed forward by feed rolls 14. These are mounted on shafts 15 and these shafts are mounted in bearings 16. A gear 17 is fixed on the lower shaft 15 and meshes with a gear 18 fixed on the shaft 19, which shaft 19 is journaled in bearings 20. A crank 21 is fixed on the shaft 21 in alinement with the shaft 19. The shaft 21 is journaled in a bearing 21*. The crank 21 is oscillated by a rod 22 from any convenient source of motion. The clutch 23 converts the rocking or oscillating movement of the shaft 21 to an intermittent forward movement in the shaft 19 and this intermittently moves the feed rolls 14 so as to advance the metal strip. The timing of the rod 22 and the punches is such that the feeding movement takes place while the punches are in their upper position and the pause in the feeding movement takes place as thepunches reach the strip.

The punched strip 13 enters the compressing rolls 24 carried by shafts 24 journaled in bearings 25. lower shaft 15 drives a gear 28 on the lower shaft 24 through the chain of intermediate gears 27. The movement of the rolls 24 corresponds to the movement of the feed rolls.

The strip 13 passes from the compressing rolls 24 to a guide 30 arranged in a guide plate 29, the guide plate having the pointed extensions 31 and 32, the extension 31 extending to a point adjacent to the bite of the rolls 24 and the point 32 extending to a'point adjacent to the bite of the resisting rolls 33. I V

The resisting rolls 33 are carried by shafts 33 and these shafts are mounted in the bearings 34. A gear 36 on the lower shaft 33 is driven from the gear 28 through the intermediate gear 35.

The gear 36 is slightly larger than the gear 28 so that the movement of the resisting rolls 33 is slower than that of the rolls 24. This variation in movement between these rolls is such that the strip 13 is compressed between these rolls so that the edges of the slots formed in the strip are forced into contact forming a strip as shown in 13*.

It will be noted that the strip 13 and 13 as formed is so slotted as to form transverse portions 37 which are connected by longitudinal portions 38 and that the longitudinal portions at opposite sides of the same transverse portion are out of alinement. This permits of the compressing movement referred to. Preferably the strip is so compressed that the edges of the slits are brought into contact. When, however, they pass beyond the roll 33 they spring apart very slightly so as to permit of plating or other operation desired, and yet they" are Within supporting distance.

By this method stays of this type can be formed using comparatively thick punches 'so that the stay may be readily fabricated and by compressing the material a greater number of crossings or transverse portions are crowded into a given length of stay. In consequence with a given flexure of the stay each crossing is subjected to a smaller twist and smaller strain and, therefore, the stay so formed will stand a greater fiexure Without taking a permanent set. At the same time the transverse portions are given a slight longi tudinal direction which subjects them to a A gear 26 on the little lateral flexure as the stay is flexed, thus.

adding to the resiliency of the stay as a whole. Bringing the edges. of the slits into supporting distance also improves the quality of the stay.

lVhat I claim as new is 1. The method of forming a garment stay which consists in slotting transversely a flat resilient metal strip, the transverse slits so made forming transverse portions joined by longitudinal portions the longitudinal portions at the opposite sides of the transverse portions being out of alinement leaving parts of the transverse portions between the longitudinal portions free to twist as the stay is flexed flatwisc and then compressing said strip lengthwise.

2. The method of forming a garment stay which consists in slotting transversely a flat resilient metal strip, the transverse slits so made forming transverse portions joined by longitudinal portions, the longitudinal portions at the opposite sides of the transverse portions being out of alinemcnt leaving parts of the transverse portions between the lon gitudinal portions free to twist as the stay is flexed fiatwise, and then compressing said strip lengthwise sufficiently to bring the edges of the slits into contact.

3. The method of forming a garment stay which consists in slotting transversely a flat resilient metal strip, the transverse slits so made forming transverse portions joined by longitudinal portions, the longitudinal portions at the opposite sides of the transverse portions being out of alinement leaving parts of the transverse portions between the longitudinal portions free to twist as the stay is flexed fiatwise, then compressing said strip lengthwise sul'liciently to bring the edges of the slits into contact, and releasing the strip and permitting a slight separation of said, edges.

In testimony whereoi l have hereunto set my hand in the presence of two subscribing witnesses.
